Dispenser adapted to deliver individual sheets from a perforated and rolled web



J. B. ENGEL 2,550,790 DISPENSER ADAFTED TO DELIVER INDIVIDUAL SHEETS FROM A PERFORATED AND ROLLED WEB 2 Sheets-Sheet 1 May 1, 1951 Filed May 10, 1948 May 1,1951 E J. B. ENGEL' DISPENSER ADAPTED TO DELIVER INDIVIDUAL SHEETS FROM A PERFORATED AND ROLLED WEB Filed May 1Q, 1948 2 Sheets-Sheet 2 IIIIIIIIIIIIIII 0 3 of the user on the free end portion thereof. As soon as the terminal sheet is severed, the roll 38 will be restored by gravity to the position shown in Fig. 4.

When the paper is exhausted, the case it] is swung downwardly to the position shown in Fig. 4, whereupon the mandrel is fully exposed for manipulation. The empty mandrel is removed from the brackets by simply lifting its pin 13 from the slots ll, 16 and withdrawing the pins 22, 24 from the'bracket [2. A new roll is then placed on the mandrel and the mandrel remounted.

The mandrel 20 is preferably made slightly wider than the core opening of the roll. However, being flat, there is plenty of clearance for the core of the roll to become slightly deformed and take an elliptical shape, the elasticity of the roll and the core holding it securely on the mandrel. With the case or cover of the device open as shown in Fig. 4, it is obviously a simple matter for the operator to engage the pin 22 of the mandrel in the opening 2! of the bracket I2 and to engage the pin 24 of the mandrel simultaneously in the lower end of slot 23. The pin H3 at the other end of the mandrel can then be inserted into the slot it of bracket l3 and the pin l8 will thereupon drop into the bearing portion ll of the slot to be firmly positioned therein for oscillatory movement as above described.

The case is preferably provided interiorly with a keeper at il (Figs. '1 and 2) which, in the closed position of the case, spans the bearing portion 17 of the slot, thus anchoring the pin it securely therein. The roll can be displaced only when the case is open.

What is claimed is:

1. In a device of the character described, the combination with a pair of spaced supports having aligned bearing apertures, one of said sup ports having an arcuate guideway substantially concentric with said aperture, of an elongated mandrel receivable into the core of a roll of paper and provided at its opposite ends with hearing pins receivable in the aligned apertures of said supports, said mandrel also having means cooperating with said guideway for limiting the oscillatory movement of the mandrel about its said aligned pins, said means and pins being at opposite sides of the center line of the mandrel and the mandrel having work supporting surfaces eccentrically disposed respecting the aligned pins, whereby the mandrel is biased by the work supported on said surface.

2. In a device of the character described, the combination with a pair of supports, one of said supports being provided with a slot opening to its end and having a downwardly recessed bearing portion, the other support having an aperture opposite said bearing portion and having an arcuate guideway substantially concentric with said aperture, together with a mandrel spanning the space between said supports and having a first pin in said slot and an aligned second pin in said aperture and an offset third pin in said guideway.

3. The device of claim 2 in which the second and third pins are at diametrically opposite sides of one end of the mandrel and both off-center from the center line of the mandrel.

4. In a device of the character described, the sub-combination which comprises a mandrel plate of elongated form provided adjacent one of its ends with an embossed channel, a pin projecting from the channel, a retaining plate having a complementary channel coacting with said mandrel plate and means connecting the mandrel plate and retaining plate to retain said pin.

5. The device of claim 4 in further combination with another projection from said plate at a point laterally spaced from said pin, and another pin at the end of said plate opposite the pin first mentioned and substantially aligned therewith.

6. The device of the character described comprising the combination with a mounting back and a case pivoted thereto and having a dispensing opening at its front, of a pair of spaced brackets connected with said back and projecting forwardly therefrom within the case, said brackets having opposing bearing apertures, one of said apertures opening through a slot to the front of its bracket, the other bracket having a second slot of arcuate form substantially concentric with its said aperture, together with a mandrel spanning the space between said brackets and having bearing pins in the respective bearing apertures, said bracket being further provided with a guide pin operating in the arcuate slot as a means of limiting oscillation of the mandrel, the mandrel being freely removable from said brackets upon disengagement of one of its pins from the bearing aperture which has the said slot opening to the end of its bracket.

'7. A device of the character described comprising the combination with a supporting back and a case pivoted thereto and provided at its front with a dispensing opening, of first and second spaced brackets connected with the back and projecting forwardly therefrom within the case, the said brackets having aligned bearing apertures one of which opens through a slot to the front of the first said bracket, the second bracket being provided with an arcuate slot concentric with its bearing aperture, and a mandrel receivable in a core of a paper roll for the mounting of said roll between said brackets, said mandrel comprising a plate having a terminal disk at one end and a pair of pins projecting beyond said disk and receivable respectively in the bearing aperture and arcuate slot of the second bracket, the said mandrel being provided at its opposite end with another pin movable into and from the bearing aperture of the first mentioned bracket through the slot opening to the end thereof.

8. The device described in claim '7 in which said plate is provided with embossed channels for said pins and has complementary retainers with cooperating channels for retaining said pins.

9. In a device of the character described, the sub-combination which comprises an elongated mandrel receivable into the core of a roll of paper, said mandrel comprising a fiat plate having parallel edges oppositel flanged to provide guide surfaces engaged with the paper roll, axially aligned embossed channels at opposite ends of the plate, a retaining plate at each end of the plate and having complementary embossed channels to overlie said first mentioned embossed channels, and axially aligned pins in said channels and projecting beyond the ends of said plate in the channels by the retaining plates.

10. The device of claim 9 further provided with an embossed channel at one end of the plate and laterally offset from said first mentioned channel at the opposite side thereof, beyond the center line of the plate, the retaining plate at said one end of the plate being provided with a '5 6 channel complementary lwitl said offset channel, UNITED STATES PATENTS and a projecting stop pin in said last mentioned Number Name Date channel between said retaining plate and said 469 301 Morgan Feb 23 1892 Plate- 1 025 312 RydquesttIZIiTl- Ma 7 1912 JOHN ENGEL- 5 1,813,853 Jackson July 7, 1931 1,897,969 Graham Feb. 14, 1933 REFERENCES CITED 7 2,229,560 Froelich Jan. 21, 1941 The following references are of record in the 2,267,962 Tishken Dec. 30, 1941 file of this patent:
